Screw pumps belong to the family of dry compressing gas transfer pumps. They are positive-displacement pumps that use two screw shaped intermeshing rotors to move gas along the screw’s axis. They are frequently used in industrial vacuum applications, often in combination with roots blowers and as oil-free roughing pumps in high and ultrahigh .

Screw conveyors, also known as auger conveyors, are widely used in various industries for the efficient movement of materials. One specific type of screw conveyor that offers unique benefits is the screw in screw conveyor. This innovative design features a screw within a screw, providing enhanced performance and versatility in handling different types of materials. In this article, we will explore the various applications of the screw in screw conveyor and delve into its functionalities and advantages.

A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline

Applications of Screw in Screw Conveyor

The screw in screw conveyor finds numerous applications across different industries due to its ability to effectively transport materials in a controlled manner. One of the notable applications of this conveyor system is in snowblowers. In snowblowers, the screw in screw conveyor is used to move snow towards an impeller, where it is then thrown into the discharge chute. This application showcases the versatility and efficiency of the screw in screw conveyor in handling even challenging materials like snow.

Types of Screw Conveyors

There are several types of screw conveyors available in the market, each designed for specific applications and material handling requirements. Some common types of screw conveyors include:

1. Inclined Screw Conveyor: Ideal for transporting materials at an incline, this type of screw conveyor is commonly used in industries where elevation changes are required.

2. Shaftless Screw Conveyor: This design eliminates the central shaft, allowing for the efficient conveyance of sticky and viscous materials without the risk of clogging.

3. Flexible Screw Conveyor: Known for its versatility, the flexible screw conveyor can be easily adjusted to different angles and configurations to suit various material handling needs.

Functionality of Screw in Screw Conveyor

The screw in screw conveyor operates on the principle of using rotating helical screws to move materials along a trough. The inner screw works in tandem with the outer screw to provide enhanced conveying efficiency and throughput. By controlling the speed and direction of rotation, operators can precisely regulate the flow of materials, making the screw in screw conveyor suitable for a wide range of applications.

Advantages of Screw in Screw Conveyor

The screw in screw conveyor offers several advantages over traditional conveyor systems, making it a preferred choice for many industries. Some key benefits include:

1. Enhanced Material Handling: The dual-screw design allows for improved material handling capabilities, making it suitable for transporting a variety of materials, including bulky or abrasive substances.

2. Increased Efficiency: The synchronized operation of the inner and outer screws results in higher conveying speeds and throughput, leading to improved productivity.

3. Reduced Maintenance: With fewer moving parts and a robust design, the screw in screw conveyor requires minimal maintenance, reducing downtime and operational costs.

The "grain auger" is used in agriculture to move grain from trucks, grain carts, or grain trailers into grain storage bins (from where it is later removed by gravity chutes at the bottom). A grain auger may be powered by an electric motor; a See more
